Seven of the 10 Aam Aadmi Party (AAP) Rajya Sabha members joined the Bharatiya Janata Party (BJP) on April 24.
The anti-defection law, in the Tenth Schedule of the Constitution, aims to curb floor-crossing by legislators.
The Tenth Schedule originally had a "split" exception, removed in 2003, and a "merger" exception, which remains.
A key point of contention is whether the conditions for a valid "merger" require both a party merger and legislative party consent.
Detailed Insights:
The anti-defection law disqualifies legislators who voluntarily leave their party or defy party directives when voting.
The "merger" exception allows legislators to join another party if their original party merges with that party, provided at least two-thirds of the legislature party agree.
The interpretation of the "merger" exception is debated, specifically whether a "deemed" merger occurs with two-thirds of the legislature party's consent, even without a party-level merger.
The Supreme Court has previously ruled that a split in the legislature party must stem from a corresponding split in the original political party.
In 2019, the Goa Legislative Assembly rejected disqualification petitions after Indian National Congress MLAs joined the BJP, claiming a valid merger.
The Bombay High Court upheld the decision, ruling that a "deemed" merger is triggered when two-thirds of a legislature party agrees to join another party.
Experts suggest a valid merger requires the original party to merge first, followed by the support of two-thirds of the legislature party.
A potential anomaly exists as Rajya Sabha MPs are elected by state MLAs, creating a disconnect if the MPs switch parties while the MLAs remain in the original party.
Key Concepts Involved:
Anti-Defection Law: Law to prevent legislators from changing parties, ensuring stability.
Tenth Schedule: Constitutional amendment that contains provisions related to the disqualification of Members of Parliament and state legislatures on grounds of defection.
